SPECIFICATION forming part of Letters Patent No. 574,334, dated December29, 1896.

Application led January 20, 1896. Serial No. 576,176. lNo model.)

, T a/ZZ wir/0m, t may concern:

Be it known that I, THOMAS R. KENNEDY, of Rochester, in the county ofl\;'[onroe and State of New York, have invented certain new and usefulImprovements in Stoves; and I do hereby declare the following to be afull, clear, and exact description of the same, reference being had tothe accompanying drawings, forming a part of this speciiication, and tothe letters of reference marked thereon.

My present invention relates to improvements in stoves, and has for itsobject to improve the construction and operation of the grate-frame,whereby it may be readily removed for the purposes of repairs orinspection; and it consists in certain improvements. all as will behereinafter fully described, and the novel features pointed out intheclaims at the end of this specification.

In the drawings, Figure 1 is a perspective view of the front of a stoveprovided with my improvements; Fig. 2, a similar vicw showing thegrate-frame removed; Fig. 2, a similar view of the detachable frontsection; Fig. 3, a longitudinal section of the front; Fig. 4, ahorizontal sectional View on the line 4: 4 of Fig. 3; Fig. 5, a verticalsectional view of one end of the grate-frame, showing it in position inthe stove-body; Fig. 6, a perspective view showing in outline amodification of the invention shown in Figs. 1 to +L; Fig. 7, a hori-Zontal section of the same.

Similar reference-letters in the several ures indicate similar parts.

The body or casingA of the stove is of the usual or any preferredconstruction, being provided with an oven B, an ash-pit C, preferablyextending forward of the front line of the stove-casing, and a frontcasing portion D, which is provider with the ash-pit door E, closingagainst the f. nt and secured by the usual projectionp and catch p. Thedoor E is also provided with the usual draft damper or slide p2.

F indicates a fire-brick lining for the firepot, said lining beingsupported in a frame F in the usual or any preferred manner.

G indicates a hearth-plate extending over the ash-pit C and in thepreferred embodiment of my invention arranged to slide on the upper edgeof the ends of the ash-pit and to hangdown at the front when desired topermit access to the ash-pan C', as shown in Fig. 2, suitable lugs gthereon passing beneath the side flanges CX, the slot C2 being providedfor the purpose. l The grate-frame, the construction and operation cfwhich forms the principal subject of my present invention, isconstructed with a top frame J, preferably rectangular, and end platesK, attached to the under side of said frame J in any suitable manner andprovided with suitable journals for the rotating grate-sections L,provided with intermeshing gear-segments L or other devices for causingtheirsim ultaneous operation, and one of them is provided with anextended journal L2, to the end of which a movable operating-handle maybe applied for the purpose of operating the grate in the usual manner.The ends K of the grate-frame, instead of being rigidly attached to theframe of the stove, rest upon suitable ways M, formed on the stove-body,and in the present instance in the form of flanges,\vhich extend thewhole length of the side walls of the ash-pit, and the lower parts -ofthe plates K, which ride upon these ways, are cut away, as shown at 7c,for the purpose of diminishing friction on the ways when the frame ismoved out to the front, as shown in Fig` 2, and on their inner lowersides said plates K are provided with flanges c,as shown particularly inFig; 5, operating to prevent ashes falling from the grate-frame lodgingon the ways M, and serving to direct them into the ash-panC.

ln normal position the grate-frame is arranged Within the casing andbeneath the tire-pot, and the parts of the stove-front D which are cutaway to permit the passage of the grate-frame are closed by plates D D2,the former being constructed, as shown in Fig. 2, with the aperture dfor the accommodation of the journal L2 of the operating grate-sectionand at the front upper portion with a suitable securing device, in thepresent instance in the form of a turn-button d', which when turned tothe position in full lines in said figure will engage the overhangingedge of the front plate D. The plate D2 is preferably attached to orformed integral with the grate-frame and is provided with a pivotedcatch e, adapted to cooperate with a lugf, formed on the front plate D,for the purpose of holding the grate -frame securely within thestove-casing. As the door E closes against the removable section D' andis secured by the catch p p', the grate-frame will ICO be held securelyeven if the catch e should become un'fastened, the grate may be operatedand dumped without danger of dust, and The draft may be regulatedentirely by the damper in the door, so that said door need not beoperated excepting for the purpose of removing the grate or ashes.iVhile this double fastening for the frame might not be necessary for agrate-frame in which there is no movable shaking or dumping section, itis particularly desirable in the form of grate shown.

From this construction it will be seen that if the invention is appliedto a stove having a sliding hearth G, when it is necessary to remove thegrate for the purpose of repairs or otherwise it is only necessary toslide the hearth out and drop it to the position shown in Fig. 2,disengage the turn-button (Z and the catch e, and then slide the grateout at the front, it being supported above the extended ash-pit, so thatany ashes adhering to it may drop into the latter and prevent soilingthe floor, and any of the parts of the grate-frame, or the whole, may beremoved as desired. This feature of moving the grate out upon waysformed upon the stove-body is very desirable, and it insures the properpositioning of the parts and enables repairs to be made without thenecessity of the operators lifting and handling large and heavy parts.

In order that the sides II of the grate-f rame may be prevented fromwarping inward,I provide upon the rear of the ash-pit, which constitutesthe front wall of the oven, suitable lugs N, adapted to engage the innersides of the plates K, as shown particularly in Fig. t, and also provideupon the removable front section D' a projecting lug g for the samepurpose.

In the construction shown in Figs. U and 7, instead of employingalooseremovable front section D', which in the other arrangement was forpermitting the removal of the grateoperating shaft, I secure theremovable platesections D3 to the grate-frame and fasten them inposition by catches o, similar to catches c, the grate-section in thisinstance being provided with a removable operatingshaft P,longitudinally mova ble,and provided with a lug s, engaged by aremovable plate s', as shown in Fig. 7, iu which arrangement it is onlynecessary to remove the plate S, slide the sha-ft ID outward until itsend is disengaged from the grate-section, then disengage the catches D3and slide the grate-frame to the front, as before.

It will be understood that the invention can be well applied to stoveswhich have a stationary hearth or other outwardly-extending ways, thegrate-frame then sliding out upon the hearth, which of course affords asubstantial support, bnt it is preferable in such a construction asshown, though I do not desire to be confined to this arrangement.

The advantage of a construction in which the grate-frame is madeindependent of the fire-brick support is obvious, as the parts liable tobecome warped or burned out may be readily replaced by very simpleoperations and without dismantling the whole stove.

I claim as my inventionl. The combination with the stove-easing, thefire-pot therein, the ash-pit and ways at the sides thereof extendingout beyond the stove-easing, of the grate-frame independent of thelire-pot, having one or more movable grate-sections therein, saidgrate-frame being movable on the ways and beneath the iirepot, anddetachable locking devices for fastening the grate-frame in positionbeneath the lire-pot, to prevent movement when the grate-section isoperated, substantially as de scribed.

2. The combination with a stove-easing, the iire-pot therein, theash-pit and ways at the sides thereof extending out beyond thestoveeasing, of the frame having the shakin g and dumping grate-sectiontherein and movable on the ways and beneath the fire-pot, the ash pitdoor hinged to the casing, securing devices therefor, a-nd thestove-casing section engaging the grate-frame and engaged and held bythe ash-pit door, substantially as de scribed.

The combination with the stove-easing, the fire-pot therein, the ash-pitand ways at the sides thereof extending out beyond the stove-casing, ofthe frame movable on the ways and having the movable grate thereinprovided with the extended operating-shaft L2, a catch between thegrate-frame and casing, the removable casing-section D', and a fasteningdevice therefor, substantially as described.

4. The combination with the stove having the ways extending out beyondthe casing and at the sides of the ash-pit, of the grateframe movable onthe ways, the movable grate thereon having the operating-shaftextension, the removable easing-section, and securing devices forattaching it to the stove-casing, substantially as described.

5. The combination with the stove, having the lire-pot, the ash-pit andsupports at the sides thereof, of the removable grate-frame, having theend plates resting and movable upon the supports, and the lugs in thestovecasing engaging the end plates of the grateframe when the frame isin the casing to prevent warping, substantially as described.

6. The combination with the stove having the fire-pot, the ash-pitextended as shown, the ways at the side of the ash-pit, and the movablehearth-plate, of the grate-frame sliding on the ways, and having themovable grate-sections and the operating-shaft, the removablecasing-section D, the catch d', the catch e, and the ash-pit door,substantially as described.
